A half-dozen lawmakers called on New York City public schools Tuesday to offer kosher and halal meals — although they couldn’t say how many students would want them.

“The mechanics we’ll leave” to the city’s Department of Education, said Public Advocate Letitia James.

She pointed out at a City Hall press conference with other legislators and Comptroller Scott Stringer that many public-school students are practicing Jews and Muslims.

Assemblyman David Weprin (D-Queens) said he’ll introduce a companion bill to state Senate legislation that would require halal or kosher options in schools where more than 25 percent of the students request them.

Weprin insisted the cost would be “minimum versus the beneficial effect.”

City Hall officials said schools already offer food alternatives.

“We work to accommodate the nutritional needs of our students, including offering daily vegetarian options,” said mayoral spokesman Austin Finan.

NEST+M high school junior Syed Islam said most observant students now have to buy their lunches, creating a financial burden.

“When children do not have money in their wallets, they tend to not eat anything,” he said.
